Do you type on your notebook while driving? That's illegal in parts of the US, even on phones.
I’m sure some of these so-called “consultants” (with jobs of which nobody knows what they actually are about) that pretend to be ever so busy would even work while they are driving (of course only if everybody can see how busy they are). The only question would be why it has to be an iPad unless it’s just for their ego.
I would suspect there will be a wave of multitouch tablets coming onto the market now because of the iPad. Which is good, it will help drive the price down.
Still, it's got to have a killer app... what is that going to be I wonder? Without this, Apple won't be able to widen the appeal beyond the Apple fanboys. I scanned the article drdr linked to and the functions they mentioned "business" people will be using this thing for are email on-the-go, taking notes on-the-go, and drawing flowcharts in meetings. The iwork software they mentioned might be the killer app, but still doesn't really provide anything "killer".
Investors are already betting iPad sales will exceed the other frenzy seen two years ago, when Apple sold 1.12 million iPhones during its first complete quarter of sales. In fact, in a little less than a year iPad unit sales are expected to exceed the estimated 3 million Kindles that have sold to date.
